Only reason for hesitation was that I don't currently have a I-out dac. It's in my long term plans and I have now managed to read my way through ~20pages of this thread and ~30 pages of the build thread, the things I do when I'm procrastinating eh.

well perhaps if someone posts a thread in the GB section proper we'll make the 50 from new people that dont check this thread religiously like those here so far =)

just a few observations (not demands it works well as is) can I plead for a slightly larger section for the output caps, a bit more space for the PSU output caps so that a lower profile part can be used and maybe a tiny bit more room around the PSU heatsinks so that more than that one model can be used? they get a little toasty in idle when ambient is warm and that would be easy fixed by using something like the type used on the Sigma11/22 PSU

so yeah i'm down with splitting the work with Do; he can do north America and i'll do ROW, or split down the middle, pcb only wont be pricey even from here. Since theres only a few people wanting fets i'll see what I can do, since i've got easy enough left here and will have to do it for mine. perhaps I can get a hand from hochopeper and i'll work out an active heating arrangement for the heatsink so I can do it at any time of the day. but still no promises, we'll see where i'm at, I can probably slightly loosen my matching requirements and find some sets in what Ive already tested tbh

getting the heatsinks again might be possible, but tbh i've had really bad luck getting them to reply to anything at all this year, so hesitate to recommend it.

since this IV really dominates and limits the choice of enclosure, what we could perhaps do is decide on a smallish power amp enclosure from siliconray (just a suggestion/option) and get a customized case made, that has a nice thick floor and heatsinks that can be well thermally coupled to the base.

thoughts?

Happy to help out mate, if you even want to split the pcbs and I'll pack/send a bunch and you can do a different set, depends on qty's etc I'm sure we can work out something that keeps the workload reduced.

I'd be keen on heatsink rather than enclosures at this stage. Though I'm really trying not to divert much money to this project until I have a DAC to go with it ...

well i'm the opposite, getting another heatsink this size would require getting a custom enclosure anyway, as fitting 2 of these beasts plus all the extras that make up a modern dac in a case just isnt going to happen, so may as well get a custom case that can do the heatsinking. any format that sinks the heat to panels that have external surfaces is good in my book, this thing can get pretty toasty

to be clear, before there is more people asking for fets, i'm not keen, I will not be doing another set to cater for the GB like last time. but the people already on the list asking for fets might be lucky
